[hpsdr] Interesting New Part from Intel

[Chris Albertson]

Technically yes, I think it can be done now.   But I don't think they are
cheap enough to be left outdoors 24x7.  And the weight is not quite
low enough to hang from a dipole.

But mounting in a box on the ground with an antenna feed only as long
as the height of the antenna is reasonable.

Anyway, my point was that with this new chip the hard CPU does not
replace the soft core CPU, it replaces the PC thereby eliminating
the USB or Eithernet "pipe"   I'd bet even the fpga development
software could run on the Atom too.
